SHEETZUFZ INVEN'TOR CLARENCE W. ANDER ON ATTORNEYS TEXTILE YARN CARRIERWITII IMPROVED STARTING MEANS This invention relates to a textile yarncarrier for use in winding yarn packages and more particularly to atextile yarn carrier including improved means to facilitate the startingof the winding of a yarn package.

In the production of yarn, it is customary practice to wind the finishedyarn on spools,.bobbins or other type textile yam carriers to form apackage suitable for storage, shipment or subsequent use. The winding ofthe package is usually started by rotating the carrier at a relativelyhigh speed and frictionally engaging the yarn with the rotating carrierso as to cause incipient winding of the yarn onto the carrier.

It is readily apparent that the design of the textile yarn carrier is animportant factor to be considered in how effectively the yarn may bestarted on the carrier. Numerous carrier designs have been providedincluding carriers having a circumferential yarn-receiving groove andcarriers having an adhesive disposed thereon. These types of textileyarn carriers have not proven to be satisfactory in many instancesbecause they provide erratic results due to moisture and other variablesinfluencing paper stability, provide inconsistant frictional contactbetween the yarn and the carrier to start winding of the yarn and in thecase of adhesives, the adhesives damage a portion of the yarn wound onthe package.

Accordingly, it is the object of the present invention to provide atextile yarn carrier having improved means for frictionally engaging andholding yarn brought into contact therewith to facilitate the startingof the winding of a yarn package and which means does not otherwisedamage the yarn wound on the package.

By this invention the above object and others are accom plished byproviding a textile yarn carrier which comprises an elongate core havinga supporting surface and a yarn-receiving groove disposed in thesupporting surface and extending at least partially around the core, andyarn catch insert means mounted within the groove for catching the yarnto facilitate the starting of the winding of a package.

Preferably, the insert means includes a base secured within the grooveto the core and a plurality of yam-catching fingers extending outwardlyfrom the base at an acute angle and terminating within the groove todefine a yarn pinch area between the base and the fingers forfrictionally engaging and grasping the yarn as it is brought within thegroove. In addition, the insert means preferably includes a plurality ofbarbs extending outwardly from the base at an acute angle and upwardlyof the groove and engaging the core for mounting the insert means withinthe groove.

FIG. 12 is a perspective view, with portions broken away, generallysimilar to FIG. 4, but utilizing the yarn catch insert of FIG. 11.

Referring more specifically to the drawings wherein like referencecharacters are employed to indicate like parts, there is shown in FIG. Ia textile yarn carrier, generally designated at 10, of the presentinvention. The textile carrier I0 is for winding yarn thereon to form ayarn package for storage, shipment or subsequent use of the yarn andcomprises a core 11 having a yarn-supporting surface 12 and ayarn-receiving groove I3 disposed in the supporting surface 12 andextending at least partially around the core 11.

The core 11 may be fabricated from any suitable material, such as paper,wood, metal, plastic and the like, and may take on any conventionalshape well known in the textile art, such as cylindrical, conical etc.In the present instance, the core 11 is an elongate, substantiallycylindrical paper tube formed by convolute winding to include aplurality of convolute windings lla (FIG. 4) with the outer surface oftube providing the supporting surface 12 for the yarn during winding.

The yam-receiving groove 13 is circumferentially disposed at leastpartially around the core 11 and preferably adjacent one end thereof sothat the winding may be started adjacent one end. The groove 13 isgenerally V-shaped in transverse cross section and extends inwardly fromthe supporting surface 12 toward the longitudinal axis of the core 11.The dimensions of the groove I3 are .not critical to the presentinvention but the depth of the groove should be commensurate with thewall thickness of the tube and the opening of the groove, that is, thelength of a line connecting the sides of the groove adjacent thesupporting surface 12, should accommodate the yarn to be used.

The textile carrier 10 asthus far described is well known in the textileart and is used by being mounted upon a mandrel or other means forrotation about the longitudinal axis thereof. During the rotation of thecarrier 10, the yarn to be wound is brought within the groove 13 wherethe yarn is frictionally engaged by the sides of the groove 13 to causeincipient winding of the yarn onto the textile yarn carrier 10 to form ayarn package. However, in many instances, the frictional contact betweenthe core 11 and the yarn is not sufficient to cause incipient winding.

To improve the ability of the textile yarn carrier 10 to catch the yarnas it is brought within the yam-receiving groove 13, the textile yarncarrier 10 of the present invention includes yarn catch insert meansmounted within the groove 13 for catching the yarn. The yarn catchinsert means, generally stated, comprises a base secured within thegroove 13 to the core I l and a plurality of yam-catching fingersextending outwardly from the base and terminating within the groove 13for frictionally engaging and grasping the yarn as it is brought withinthe groove I3. Preferably, some of the yam-catching fingers extendoutwardly from the base at an acute angle downwardly further within thegroove I3 to define a yarn pinch area between the base and each of thefingers. Furthermore, in order to mount the yarn catch insert within thegroove I3 to the core 11, it is preferable that the insert include aplurality of barbs extending outwardly from the base at an acute angleupwardly of the groove 13 and engaging the core 11. It will readily beapparent that the rapid rotation of the textile carrier I0 will notcause the yarn catch insert to be thrown from the groove 13 since thegreater the centrifugal force on the insert the more the barbs willpress against and penetrate the core II.

A preferred embodiment of the yam-catching insert means, generallydesignated at 20, is employed in the textile carrier I0 of FIG. I and isbest illustrated in FIGS. 2-4. Referring to FIG. 4, the yam-catchinginsert means 20 comprises an elongate base 21 having a generallyV-shaped cross section wedged within or mating with V-shaped groove 13.A plurality of barbs 22 extend outwardly from the outside of the V-shaped base at an acute angle upwardly of the groove 13 in engagementwith the portions of the core 11 defining groove 13 for securing theinsert 20 within the groove 13. It will be appreciated that the barbs 22allow the insert 20 to be selfsecured within the groove 13 in such amanner that the insert 20 will not be pulled or thrown from the groove13 during use of the textile carrier 10. In order to catch the yarn whenbrought within the groove 13, the insert 20 includes a plurality ofyarn-catching fingers 23 which extend outwardly from the inside of theV-shaped base 21 at an acute angle downwardly further within the groove13 to define a yarn pinch area 24 between the inside of the V-shapedbase 21 and each of the fingers 23. Thus, when a yarn is placed inwardlyof the groove 13, it will catch on one or more of the yarn catch fingers23 and be pinched between the catch fingers 23 and base 21 to start thewinding of the yarn on the supporting surface 12 of the core 11. Whilethe length of the insert 20 is not extremely critical, it is preferredto have a plurality of spaced-apart discrete inserts similar to thatillustrated in FIG. 4 rather than a continuous insert extending alongthe entire length of groove 13.

The yarn catch insert 20 of FIG. 4 may be formed of plastic, metal,wood, or other suitable material by any conventional techniques such asextruding, casting or the like. There is illustrated in FIG. 2 a roll orstrip S of material that has been extruded to include the base 21, barbs22 and yarn-catching fingers 23 and may be-folded at its center into thegenerally V- shape shown in FIG. 3. From the V-shape in FIG. 3 the stripS may be cut into discrete segments along cut lines CL to form discreteinserts 20 which may be wedged within groove 13 as in FIG. 4 to completethe textile yarn carrier 10.

A slightly modified yarn catching insert 20' is shown in FIGS. 5 and 6and, due to the similarity with insert 20, insert 20' is given the samereference designation with the addition of a prime notation. Themodified insert 20 includes a generally V-shaped base 21, a plurality ofbarbs 22' for securing the insert within the groove 13 and a pluralityof yamcatching fingers 23 extending outwardly from the inside of theV-shaped base at an acute angle downwardly further within the base todefine a yarn pinch area 24' between the base 21' and each of thefingers 23'. Insert 20' difi'ers primarily in the manner in which it isformed and the materials from which it is preferably made. The insert 20is preferably formed from a rigid material such as metal or plastic andis formed initially to include the generally V-shape whereby additionalforming is unnecessary.

Another slightly modified yarn catch insert 20" is shown in FIGS. 11 and12 and, due to the similarity with inserts 20 and 20', this insert isgiven the same reference designation with the addition of a double-primenotation. This yarn catch insert 20" may be formed of a strip S ofplastic or other suitable material which has been punched to form apattern of fingers, as indicated in FIG. 11. As indicated in FIG. 11,the strip S may be cut into suitable lengths and folded to form agenerally V-shaped base 21" having a plurality of barbs 22" for securingthe insert within a groove 13 of a carrier and a plurality of yarn catchfingers 23" extending outwardly from the inside of the V-shaped base 21at an acute angle downwardly further within the base to define a yarnpinch area 24" between the base 21" and each of the fingers 23'. Insertdiffers primarily in the manner in which it is formed and is securedwithin the groove 13 in the same manner as the inserts 20 and 20described above to provide for ease in entry of the yarn into the insertbut extreme difficulty in the yarn escaping therefrom.

Other modified forms of the yarn catch insert of the present inventionwill be readily apparent and by way of example, two such modifiedinserts and 40 are illustrated in FIGS. 7 and 8 and FIGS. 9 and 10,respectively. Referring to FIGS. 7 and 8, the modified insert 30comprises an elongate base 31 of less length than the depth of V-shapedgroove 13. One end of the elongate base 31 has a plurality of barbs 32extending outwardly therefrom at an acute angle upwardly toward theother end of the elongate base 31 and serve to secure the elongate base31 within the groove as shown in FIG. 8. The other or free end of theelongate base 31 which extends outwardly from the bottom of the groove13 has a plurality of yarncatching fingers 33 which extend outwardlyfrom adjacent the free end of the base 31 at an acute angle anddownwardly further within groove 13 to define a yarn pinch area 34between the base 31 and each of the fingers 33.

With reference to FIGS. 9 and 10, the modified insert 40 comprises anelongate rod or base 41 having a diameter less than the opening ofgroove 13 whereby it can be placed lengthwise within the groove 13 asshown in FIG. 10. The elongate base 41 has a multitude of barbs 42extending outwardly therefrom at spaced intervals throughout the lengthand circumference thereof. Preferably, at least some of the barbs 42extend outwardly at an acute angle from the base 41. When the insert 40is placed lengthwise within groove 13 as shown in FIG. 10, a portion ofthe barbs 42 serve to mount the insert 40 within the groove 13 byengaging and partially penetrating the core 1 1. Another portion of thebarbs 42 serve as yarn-catching fingers for frictionally engaging andgrasping the yarn as it is brought within groove 13. If, as preferred,numerous of the barbs 42 extend outwardly at an acute angle from thebase 41, a portion of these barbs 42 will define a yarn pinch areabetween the barbs 42 and base 41. In addition, the securement of theinsert 40 within the groove 13 will be improved, that is, if the barbs42 extend upwardly of the groove 13 and engage the core 11.

The use of the textile carrier 10 heretofore described is readilyapparent. The textile yarn carrier 10 is mounted upon a spindle or othermeans for rotation about the longitudinal axis thereof. The yarn to bewound is brought within groove 13 at which time the yarn is frictionallyengaged and grasped by the yam-catching fingers of the insert to startthe winding of the yarn to form a yarn package. Preferably, the yarn iscaught in the pinch area between the yarn-catching fingers and base ofthe insert. During rotation of the textile carrier 10, the yam-catchinginsert will not be thrown from the groove 13 since the pull the yarncreates on the insert and the centrifugal force from the rotation of thetextile carrier will cause the insert to be more securely held withinthe groove 13.

From the foregoing description it is readily apparent that there hasbeen provided a textile yarn carrier which includes improved means tofacilitate the starting of the winding of yarn thereon which is botheconomical of manufacture and easy to use.

In the drawings and specification, there has been set forth a preferredembodiment of the invention and, although specific terms are employed,they are used in a generic and descriptive sense only and not forpurposes of limitation.
